7x = -67 - 11v<br> 5x = -73 - 11v

Burka [1]

Answer:

x = 3, v = -8

Step-by-step explanation:

Substitute x.

$\frac{-67-11v}{7}$

[5 • $\frac{-67-11v}{7}$ = -73 - 11v]

Isolate v.

5 $\frac{-67-11v}{7}$ = -73 - 11v

v = -8

Substitute v.

x = $\frac{-67-11(-8)}{7}$

x = 3

Given parallelogram abcd, find the value of y.

nekit [7.7K]

Answer:

c) 82

Step-by-step explanation:

<ABE and <BEC are supplementary because they form a line.

<ABE + <BEC = 180

116+ x = 180

Subtract 116 from each side.

116-116+x = 180 -116

x = 64

The angles in triangle ECB add to 180 because it is a triangle

<BEC + <ECB + <CBE = 180

x + 34+y = 180

64 + 34+ y = 180

98 + y = 180

Subtract 98 from each side.

98-98+y = 180-98

y = 82
